Well-differentiated liposarcoma of the paratesticular area: report of a case with fine-needle aspiration preoperative diagnosis and review of the literature.
This article presents a rare case of well-differentiated liposarcoma of the paratesticular area (spermatic cord) with a preoperative cytological diagnosis. A 0.6-mm fine-needle aspiration biopsy (FNAB) of a paratesticular lump showed many spindle and polygonal atypical cells with numerous cytoplasmic vacuoles. On the basis of a diagnosis of "malignant mesenchymal neoplasia consistent with liposarcoma," the patient underwent radical orchiectomy. A 8 x 7 x 8.5 cm, whitish mass was found, which was histologically classified as a "well-differentiated liposarcoma" (with lipoma-like, sclerosing, and myxoid areas), according to the classification of Enzinger and Weiss. A review of the literature is presented.
